A progress update from Angrywasp on discord, hardfork will happen in a couple weeks:

Jus a quick update. Ledger support for version 2 bulletproofs has passed initial testing and is ready for the testnet. Some patches to the PoW algorithm will be rolled into this release as well, which i am part the way through done. Got to finish that and get the ledger app packaged up for distribution and we should be good to go for some public testing with a view to a hardfork in the next couple of weeks. Got some other handy new features too, like autodetecting the optimal number of mining threads for the daemon, syncing from external checkpoint files, fixes to the slow syncing which has been a problem for a while. Also added the daemon code for the woocommerce plugin to not require a locally running daemon and wallet, which will please @ukminer, and have a bit more work to do on the plugin side for that. So overall, going to be a good update. Fixed some problems and got some new goodies. I will advise when the testnet is updated so we can get some testing on the new bulletproofs and ledger, which should be in the next 2-3 days.
